Question

If cos0=25/25 then find sin0 and tan0 without using identity. Also fin sin20+cos20​

Answer 1

Step-by-step explanation:

Given that:-

Cos O=25/25

=>Cos O=1

=>Cos O= Cos 0°

=>O=0°

Now O=0°

Sin O=Sin 0°=0

Tan O=Tan 0°=0

Sin²O+Cos²O

=>Sin²0°+ Cos²0°

=>0²+1²

=>0+1

=>1

Hence, Sin²O+Cos²O=1
